The AirTAC SC40 Standard Cylinder SC40X950SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X950SH is a double-acting tie-rod cylinder delivering 628 N push and 528 N pull at 0.5 MPa (1130 N push at 0.9 MPa). With a 950 mm stroke and a 16 mm diameter piston rod, it suits long-reach actuation where heat resistance is required.
This model carries the -S magnet suffix for direct mounting of CMSG/DMSG/EMSG sensors on the barrel, and the -H Viton seal suffix, shifting the operating temperature range to 0–150 °C. The body length A is 142 mm, giving a total extended length of approximately 1092 mm.

| Max (approx.) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow the SC40X950SH to operate continuously at 0–150 °C, making it suitable for actuators near ovens, autoclaves, or drying tunnels where standard seals would degrade.
The 950 mm stroke moves parts across wide conveyor gaps or between distant stations. The built-in magnet enables end-of-stroke sensing without external flags.
Combine the -S magnet with CMSG reed sensors for precise clamp/unclamp confirmation in automated assembly cells, even under elevated ambient temperatures.
Choose the SC40 bore for moderate force in a compact tie-rod package. If you need higher thrust, step up to the SC50 (982 N push at 0.5 MPa); for lighter, space-constrained tasks, the SC32 provides 402 N. At 950 mm stroke, the 16 mm rod is unsupported over a long distance—use an external linear guide or a guided cylinder if side loads are present.
For a direct replacement, match these five points: 40 mm bore, 950 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal (-H) for high-temperature compatibility. This SC cylinder is shorter than an ISO 15552 unit and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N push and 528 N pull. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC40X950SH is a double-acting cylinder and does not lock or hold position when air is exhausted or the directional valve is centred. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
